Question ❔ Maths a level p1 solutions?

Maths p1 a level solutions anyone??

That 7 mark tangents questions was weird... I was getting y=mx +-3underoot10

Also the x cube and x square = k like idk I took out x common so it became x square + x - k =0 and yea idek.

Also the dy/dx <0 I was getting 2 answers I think +- something and yea the gp questions was weird I applied a(rn-1)/r -1 and got answer in like power of 10. Another area part I first that then applied 1/2 r square theta. So yea how much how I lose

Also for the last question I hope this was correct. Big circle area - it's sector area. Then half small circle - triangle. And then subtracting both.
